I can assign Volume Up and Volume etc RS232 codes
to soft buttons. These work on "RS232 PORT 1" just fine

But I get no result when programming the same Code into volume UP/Down Hard Buttons.

I do see RS232 Port 1 activity ligth on the front panel of the
RFX9600. But nothing happens on the device

I created a Link on Sytem Panel Property Page Volume Up/Down keys. In the same dialog I Added the appropriate RS232 Codes that work fine from my soft buttons.

I can see the link details when reviewing Device Properties Dialog

The device Properties Dialog has a TAB named settings
From this tab there is a port selection
Option:

The options however are for selecting IR ports only.

Has any one made Hard Buttons to work from a specific
when linked to a Device Page?

Tanks any help appreciated
